Austrdia? Rven if it did, it may not follow thai the v. hite 

 races would be finally ousted by climatic consequences? 

 In this connection we need to remember the important fact 

 pointed out by Professor Ward, that thousands of Italians 

 for instance, go to the United states in the spring to work 

 there during the warmer months and then return to the 

 milder (donate of Italy for the winter. Similarly incursions 

 are made into Argentina in the harvesting season. It 

 remains therefore a question for Australians to consider 

 whether people from Southern Europe may successfully be 

 invited to migrate permanently to Northern Australia. 

 Have we here a clue to the great problem of the develop- 

 ment of the sub-tropical regions of Australia? Is there 

 not a moral necessity pressing upon us to develop in the 

 best manner possible the resources, mineral, pastoral, and 

 agricultural of the regions in the northern portions of our 

 land now running to waste under ineffective management? 

 The sustained high tropical temperature of our northern 

 areas is not of that dangerous intensity created by the 

 more humid conditions of the tropics, and the diseases 

 which may be of special prevalence in warm climates are 

 not, so far as we probably know, of that deadly nature 

 which is experienced in other portions of the torrid zone. 

 Young and healthy Australians, properly educated before- 

 hand, regarding the risks and inconveniences of our sub- 

 tropical areas, will surely be forthcoming even from our 

 somewhat limited population, to supply the waste places 

 of our laud with that vigor, energy and national capital of 

 endurance whieh is requisite for the development of every 

 part .'I our territory ; and if we should also seek a judicious 



Study of Tropical Diseases. We have already at Towns- 

 ville an Institute for the study of tropical diseases, with 

 officials fullv ar, maimed with the results of research in
